You have to walk past the dessert display on your way to your table at Café Berlin, so forget your diet. These delicious homemade confections are the best reason to come here. The vast spread might include an apple strudel, raspberry Linzer torte, sour-cherry crumb cake, or vanilla-custard cake. Look for items like the rahm schnitzel, which is a center cut of veal topped with a light cream and mushroom sauce, or a wurstplatte of mixed sausages, among the entrees. Seasonal items highlight asparagus in spring, game in the fall, and so on. Lunch is a great deal: a simple chicken-salad-on-whole wheat sandwich (laced with tasty bits of mandarin orange), the soup of the day, and German potato salad, all for about $8. The owners and chef are German; co-owner Peggy Reed emphasizes that their dishes are "on the light side -- except for the beer and desserts." This 18-year-old restaurant occupies two prettily decorated dining rooms on the bottom level of three joined Capitol Hill townhouses, whose front terraces serve as an outdoor cafe in warm weather.
